Three Wobble Scan Modes
Hanli 4-in-1 Handheld Laser Welding Machine
Not every seam wants the same wobble. This build gives the operator three scan modes — circular, rectangular and linear — so fillets, wide joints and fast straight runs each get the pattern that suits them. An integrated Hanli chiller and smart optical-path protection keep the four-in-one platform welding, cleaning, cutting and finishing seam after seam, 1500W to 3000W.

Overview
Pattern Control Is What Makes a Bead
The wobble head is the most misunderstood part of a laser welder. It does not simply widen the spot; the shape it traces changes how heat spreads, how the pool behaves and how much fit-up tolerance the joint can absorb. Three modes give the operator that control.
- Three scan modesCircular, rectangular and linear, each tuned for a different joint family.
- Optimised fill modeA denser pattern that fills a joint more evenly and improves appearance.
- Smart optical-path protectionReal-time monitoring of temperature, gas pressure and laser status during welding.
- Integrated Hanli chillerA compact chiller inside the cabinet keeps the source and optics cool.

Signature Module
Circular, Rectangular or Linear?
The wobble path is chosen by joint type, not by habit. Here is how the three patterns differ.
Circular
Spreads heat evenly in every direction. Best for fillets and corners where the weld must wet both faces of the joint equally.
Rectangular
Covers a wide band across the joint. Improves gap bridging on butt and lap welds and builds a broad, flat bead.
Linear
Runs a fast, narrow pass along a straight seam. The highest travel speed, ideal on thin sheet where heat must stay low.
| Scan Mode | Best Joint | Gap Bridging | Travel Speed |
|---|---|---|---|
| Circular | Fillet, corner, T-joint | Good in all directions | Medium |
| Rectangular | Butt, lap, wide joint | Best across the joint | Medium |
| Linear | Straight thin-sheet seam | Lower, needs tight fit | Highest |

Operating Routine
Pick the Pattern, Then Run the Seam
Four steps take the operator from a cold machine to a dressed, inspected seam.
01
Choose the Mode
Select circular, rectangular or linear according to the joint type and the fit-up you have.
02
Clean the Joint
Run the cleaning head along the seam to remove rust, oil and coating before welding.
03
Weld the Run
Set power, frequency and wire feed, then run the joint in a single controlled pass.
04
Dress and Check
Finish with the seam-cleaning head and compare bead width and penetration to the sample.
Core Advantages
Protection Built Into the Beam Path
Three features that keep the machine accurate and cheap to run.
Optical-Path Protection
Temperature, gas pressure and laser status are monitored continuously, so a drifting parameter is flagged early.
High-Threshold Optics
Higher-grade optical elements lift the damage threshold, which improves weld quality and lengthens lens life.
Drawer-Type Lenses
Focus and protective lenses slide out for cleaning or replacement, so routine service takes minutes.
Applications
Where Pattern Control Matters Most
Mixed-joint workshops get the most from three scan modes.
Automotive & Repair
Mixed fillet and butt joints on brackets, panels and exhaust work.
Stainless Fabrication
Sinks, tanks and railings where the seam must finish bright without pickling.
Sheet Metal Enclosures
Cabinet corners in fillet mode and straight runs in linear mode on the same machine.
Heavy Metalworking
Thicker frames welded at 2000W to 3000W with rectangular scan and wire feed.

FAQ
Hanli Scan Mode and Cooling Questions
Circular suits fillets and corners because it spreads heat in every direction. Rectangular covers wide butt and lap joints and improves gap bridging. Linear runs a fast narrow pass along a straight seam for higher travel speed on thin sheet.
It watches the working state of the beam path and the machine in real time. If a lens is soiled, a connector overheats or a parameter drifts, the system flags it before the fault reaches the optics, which protects the weld quality.
The focus and protective lenses use a modular drawer-type mount. They slide out for cleaning or replacement without a full realignment, which keeps routine maintenance inside a few minutes.
The Hanli chiller uses dual temperature control to hold the laser source and the optics at their own set points, keeping stability within about 0.5 to 1 degree Celsius for consistent output.
Yes. The chiller uses R410A refrigerant and runs quietly, which suits workshops that are sensitive to noise. Multiple alarm systems guard against overheating, over-current and water flow faults.
Stainless steel, carbon steel, aluminium, copper and galvanised sheet are all supported. Aluminium and copper reflect more of the beam, so they are welded at the higher power levels with a different focus and gas setting.
Standard production is about five working days, with express transit adding roughly four to six working days. The machine carries a 2-year warranty with free replacement parts and English online support for the life of the unit. Volume terms are agreed per order.
